A:AnswerHi birdhunter1905, For optimum performance, we recommend using phone purchased in the US not to be used in a different country as these are designed for US specifications.
A:AnswerYes, the supplied handset (KX-TGA660) does have a headset jack. And so is the compatible handset KX-TGA659. However, another compatible handset, KX-TGA410 does not have a headset jack.
